Answer:
8 gram
Explanation:
in case of NaOH, normality=molarity
so normality=molarity×acidity or basicity(in case of NaOH it's 1)
then
weight of NaOH required = volume in ml × equivalent weight × normality / 1000
so
1000× 40× 0.2/1000
=8 gram
Answer:
The chemical equation by putting, a 2 on C₅H₁₂O, 15 on O₂, 10 on CO₂ , and 12 on H₂O in the equation;
2C₅H₁₂O + 15O₂ → 10CO₂ + 12H₂O
Explanation:
- Chemical equations are balanced by putting coefficients on the reactants and products to ensure the total number of atoms on the left side equal to those on the right side.
- Balancing chemical equations is done to make chemical equations obey the law of conservation of mass.
- According to the law of conservation of mass, the mass of the reactants should always be equal to the mass of products.
- This is done by balancing chemical equations to ensure the total number of atoms on the left side is equal to that on the right side.
- Therefore, the balanced equation is;
2C₅H₁₂O + 15O₂ → 10CO₂ + 12H₂O
The answer is 3. As 5 * 3 = 15.
Is there any other equations I may be able to help you with? :)
